Sure. So, as we mentioned, we are planning on launching in the second half of the year as soon as we finished our clinical validation study. And as I mentioned in the discussion here, our first intended use is going to be Lung RADS 4. That again is nodules which are eight millimeters and larger. And those today, as we mentioned, we think that there is that that's about 4% of the overall population with long nodules. So, it's probably in the 400,000 to 600,000 patients per year range. Now, assuming that all patients got their screening test, number of screening tests that is going on is increasing fairly rapidly, so it is a rapidly growing market. So, that bakes to the potential addressable market. As we also mentioned, given that we are doing studies, our studies with lung nodule sizes right down to five millimeters, we believe that we have a potential second indication in Lung RADS 3 the five to eight millimeter lung nodules and that of course is another potentially up to 800,000 patients. That gets us to that 1.4 million patients per year total addressable market number. I think your second question was about reimbursement. Reimbursement, as you know, is in the lung space, in the diagnostic space in general, is it can take a number of years. And what's really important is that we are building out our product development plans, our R&D plans, as well as our commercial plans to give the highest potential opportunity for reimbursement. So, the way that CMS and other insurance companies look at this, they want to see not only the strong clinical validation studies, which we hope to complete this year, but also the ongoing clinical utility studies, which would show after launch are the doctors actually avoiding the biopsy. So, we are planning and doing enough of those that we will give the insurance companies, the CMS, the payers in general what it is that the data that they need. So, I think that it's difficult to predict the time, but we have seen with other companies with tests of this sort is it can take up to two to three years to get the reimbursement. There will be some reimbursement as we said before that. We also hope to get the coverage with data development from CMS, which is at their discretion, but that is something, which could come potentially a little faster. So, those are - I think we're facing the same kind of reimbursement challenges that the rest of the industry does, but we are building out our science and our commercial practices to try to maximize that opportunity.
